What Is PMI — and How Can Bay Area Buyers Avoid It?

If you're buying a home in San Jose or the greater Bay Area and you're not putting 20% down, there's a good chance someone has mentioned PMI to you. Private mortgage insurance can add several hundred dollars or more to your monthly payment — but it's not unavoidable, and it's not permanent.

What Is PMI?

PMI stands for private mortgage insurance. Despite the name, it doesn't protect you — it protects your lender. If you were to default on your mortgage, PMI pays the lender for a portion of their loss.

Conventional loans (backed by Fannie Mae or Freddie Mac) require PMI when your down payment is less than 20% of the purchase price.

Note: FHA loans have their own version called MIP (mortgage insurance premium), which works differently and is beyond the scope of this post.

How Much Does PMI Cost in the Bay Area?

PMI generally runs between 0.5% and 1.5% of the loan amount annually. On a $1,200,000 loan at 1% PMI, that's $12,000 per year — or $1,000 per month added to your payment. Even at 0.5%, you're looking at $500/month.

4 Strategies to Avoid or Eliminate PMI

Strategy 1 — Put 20% Down. The most direct path. In the Bay Area, this can mean a down payment of $280,000–$400,000 or more.

Strategy 2 — Piggyback Loan (80-10-10 Structure). A first mortgage for 80%, a second mortgage for 10%, and 10% down. Because neither loan individually exceeds 80% LTV, PMI isn't triggered.

Strategy 3 — Lender-Paid PMI. Some lenders cover the PMI cost themselves in exchange for a slightly higher interest rate — a cleaner monthly payment with no separate PMI line.

Strategy 4 — Request Cancellation Once You Hit 20% Equity. Federal law requires automatic cancellation once your loan balance drops to 78% of the original purchase price. You can request cancellation at 80% LTV.

A Bay Area-Specific Consideration: Appreciation Works in Your Favor

Home value appreciation counts toward equity. If you bought a home two or three years ago with 10% down, and values in your neighborhood have increased 15–20%, there's a real chance your current LTV is already at or near 80% — meaning you may be able to cancel PMI much sooner than your amortization schedule suggests. Most lenders require a formal appraisal ($500–$800) to verify current market value.

What About Jumbo Loans?

Jumbo loans — above the conforming loan limit of $832,750 in most markets for 2026 — aren't backed by Fannie Mae or Freddie Mac, so traditional PMI doesn't apply. Jumbo lenders set their own requirements; some require 20% down while others allow lower down payments without requiring PMI.

Frequently Asked Questions

Does PMI build equity for me?

No. PMI premiums go directly to the insurer — they don't reduce your loan balance or build equity.

Can I deduct PMI on my taxes?

PMI deductibility has varied over the years based on Congress — ask your CPA for current guidance.

What's the difference between PMI and MIP?

PMI applies to conventional loans. MIP applies to FHA loans, and works differently, including different cancellation rules.

Can I put 10% down on a Bay Area home and avoid PMI entirely?

Yes — through a piggyback loan structure or by choosing lender-paid PMI.
